PROBLEM TO BE SOLVED: To provide a massage machine for performing appropriate air massage without a stop feeling by suppressing an interval between operation patterns.SOLUTION: An inter-electromagnetic-valve interval TD between the same electromagnetic valves 32e, 32f and an inter-pattern interval TP between the operation patterns A, B are set in a memory beforehand. A control part subtracts from the inter-electromagnetic-valve interval TD, the inter-pattern intervals TX1, TX2 from the termination of last expansion operations of the electromagnetic valves 32e, 32f in the preceding operation pattern A till the termination of the operation pattern A and from the start of the succeeding operation pattern B till the start of the first expansion operations of the same electromagnetic valves 32e, 32f. The control part compares the subtraction result with the inter-pattern interval TP, thereby to define the larger value as the interval to be required in exhausting and the radiation of the electromagnetic valves 32e, 32f with the contraction operations of air bags between the operation patterns A, B. |
